Is there away to calculate what a run would be at a different DA. If I ran 11.87 with the DA at 1020, what would that be wih a DA of -1000 ?

 

Roughly, you can expect a difference of .01 sec for every 100ft. of altitude/DA change...

So from +1020 to -1000, you'd probably see a .2/~2mph improvement...

 

Thanks Looks like I picked up at least two tenths with the new tranny and converter. The run in my signature was at -20 DA. I was also about 60lbs lighter.

 

what trans and converter do you have now...update sig

 

I purchased them from a board member here. The trans is a 4L60E with all the usual upgrades including a trans go shift kit. The converter is a Yank PY3800E. I made four passes Saturday, sixty ft's were 1.651,1.630,1.623, & 1.622. Too bad I'll have to wait till the fall for -DA weather.
